Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

U-Boot Customization for Verdin iMX95

Unfortunately, the current documentation doesn’t include specific instructions for building U-Boot for Verdin iMX95 modules(1). The general U-Boot build documentation covers various Toradex modules including TI AM62x(2), TI AM62Px(3), and NXP i.MX 8M Mini/Plus(4), but Verdin iMX95 is not specifically documented.

Current Status of U-Boot Splash Support

Regarding your goal of showing a customized early splash logo on the native LVDS screen, there are some important limitations to be aware of:

Display Support Challenges

Based on community feedback, there are significant challenges with U-Boot display support on newer i.MX platforms(5). For i.MX8M Plus modules, which share similar architecture characteristics with iMX95, the required drivers such as imx_lcdifv3.c and sec_dsim_imx.c are not present in the current U-Boot source(5).

Upstream vs Downstream U-Boot

With recent BSP versions, Toradex has moved to upstream U-Boot, which is missing many of the i.MX drivers and code required for advanced display support(5). This transition affects display capabilities in U-Boot across the i.MX platform family.

Recommendations

  1. Check BSP Documentation: Review the Embedded Linux Release Matrix to confirm the U-Boot source and branch information for Verdin iMX95(1).

  2. Alternative Approaches: Consider implementing your splash screen at the Linux kernel level instead, where full display driver support is available.

  3. Follow General Build Process: While waiting for iMX95-specific documentation, you can reference the general U-Boot build process(1) and adapt it for your platform.

To get the most current information about your specific hardware setup, I recommend running the tdx-info command on your device to gather detailed platform information. You can find more details about this tool at: Getting Device Information with Tdx-Info | Toradex Developer Center
